Eric Wild dadabeceaf cmake: actually make linking work
Appending to lists from subdirs does not work as expected, so work
around that to allow collecting the necessary libs.

Clayton Smith 137c568c60 rtl_tcp: Throw an exception if TCP connection fails
Currently, rtl_tcp_source_c repeatedly calls ::connect until it
succeeds. This can result in 100% CPU utilization and/or a lot of
network traffic. In addition, GUI applications like Gqrx freeze up.
To solve these problems, I've changed the code to report an error
if ::connect fails.

Piotr Krysik 8cf6840da1 cmake: Go back CMake min ver. 3.8 by removing need for CMP0079
CMake 3.13 is not present in older (~2 years old)
Linux distributions and GNU Radio requires min CMake
version 3.8.

All that is needed in order to avoid bumping CMake version
is to not use 'target_link_libraries' in subdirectories.
Here this is done by creating a list of needed
libraries and adding them for linking at the end (like
it was done in gr-osmosdr before porting to GNU Radio 3.8).

One thing that is lost here is 'PRIVATE' statement in case
of FCD libraries linking.

Krzysztof Halasa 26f93e4687 RTL-TCP: Convert to single class model
The existing RTL TCP driver is quite different from its brother RTL_SDR.
It's much more complicated, uses gr::blocks::deinterleave and
gr::blocks::float_to_complex, and generally doesn't work correctly
 Spectrum is mirrored when filter or demodulator changes (rtl_tcp) #99)

I've converted the RTL TCP driver to the model used by RTL_SDR,
simplifying it in the process, and fixing the GQRX issue.

Josh Blum 9ceadfb645 rtl_tcp: fix ssize_t definition for MSVC
This was actually causing a cryptic compile error because of the define.
The fix was to typedef ssize_t as ptrdiff_t, the same as bladerf_common.h

Jeremy Visser 58d95b5164 Allows connecting to IPv6 hosts if an AAAA record is present
and /etc/gai.conf is not configured to prefer IPv4 hosts.

The current logic handling the output of getaddrinfo() is
flawed in that it only ever attempts to connect() to the
first address returned.

This is a problem for both round-robin and dual-stack hosts.

Furthermore, rtl_tcp_source_c::rtl_tcp_source_c() assumes a colon
in the device string is a port number.  This prevents the use
of raw IPv6 addresses.  The function will need to be taught how
to handle IPv6 addresses contained within square brackets, e.g.

Therefore further work is required to improve the handling of
multiple addresses, and also device strings containing raw IPv6

Dimitri Stolnikov 0edfcfcba0 rtl: remove residue DC component introduced by RTL chip
received from Juha Vierinen:

A student here noticed that there is dc bias even with the rafael tuner.
We looked into this issue and found that using 127.4f instead of 127.5f
removes this bias. I assume this is associated with a bug in the digital
downconversion of the RTL chip. This change fixes the problem.
